Smelly girly area ... help !

Elissa

I was pregnant with my second kid and gave birth a year ago . I was breast feeding so I didn’t get my period until maybe 8 months . Ever since I have the horrible smelly discharge . It’s more noticeable after my periods . No matter how many times I change or bathe it won’t go away . The smell is sooo strong I can smell it over my jeans . I don’t have insurance or the money to spend on a doctor . I just want something so I don’t smell . My husband doesn’t seem to mind but of course I’m sooo embarrassed . Anyone have any idea or should I go into the doctors ?
